Abstract: CO2 capture，utilization and storage technology is one of the key technologies to deal with global climate change. In the process of oil and gas field development，injecting the CO2 captured into oil layers can not only reduce oil viscosity，but also supplement the formation energy to improve oil recovery. In addition，CO2 can be stored underground by doing so. And so，this practice has attracted extensive attention. At present，alcohol amine absorption method is a commonly used technology for CO2 capture. However，this method has a high energy consumption for regeneration，a great loss of alcohol amine solution，and a decreased regeneration rate of CO2 with the increase of recycling times. Therefore，a new CO2 capture technology is urgently needed. Assembled by metal ions and organic ligands，metal-organic frameworks（MOFs）material is a netted framework compound，which features large porosity，high specific surface area，diversified structures and easy modification. This provides it a promising prospect in the field of CO2 capture and separation. This paper introduces the features of MOFs first，and then summarizes the synthesis methods of MOFs. Finally，the application of MOFs to CO2 capture is presented，and an outlook of its application in the development of Xinjiang Oilfield is made.

摘要： CO2捕集、利用与封存是应对全球气候变化的关键技术之一。在油气田开发过程中，将捕集的CO2注入油层中，既能降低原油黏度，又能补充地层能量提高采收率，同时还能将CO2封存到地下，因此受到了广泛的重视，目前常见的CO2捕集技术是醇胺吸收法。然而，醇胺吸收法再生能耗较高，溶液损失较大，且CO2的再生率随着循环次数的增多而降低。因此，急需一种新的CO2捕集技术。金属有机框架材料（MOFs）是一种网状框架化合物，通过金属离子与有机配体组装而成，具有大孔隙率、高比表面积、结构多样性、易修饰等特点，使得其在CO2气体捕集与分离领域有着非常好的应用前景。首先介绍了MOFs的特点，之后总结了MOFs材料的合成方法，最后介绍了MOFs材料对CO2、H2S和CH4吸附分离上的应用，并对其在新疆油田开发过程中的应用进行了展望。
